Psyllid captures slightly higher this week; one psyllid from last week Lso positive

• This week we received traps from all 55 fields that we are monitoring.
• We captured a total of 140 psyllids spread across 23 fields.
• Captures were from the following counties: Canyon, Owyhee, Elmore, Gooding, Jerome, Twin Falls, Cassia, Minidoka, Bingham, and Bannock.
• Of the 92 psyllids captured last week, one of them from Twin Falls County tested positive for Lso.
• For psyllids captured this week, we expect to have results on Lso incidence next week.
• We received one field from last week late; those traps captured 3 psyllids. We expect to have results for those psyllids next week as well.

Overall psyllid captures were slightly higher than last week, and captures were similar to those observed at this time in 2020 and 2021 (the last time we had relatively high captures). Risk of ZC continues to be moderate to low this year given this combination of moderately high psyllid captures and relatively low Lso prevalence. Psyllid captures often peak around late July to August, so we will have to see whether captures climb next week. Much of the psyllid pressure continues to be focused in the Treasure Valley. Relatively few psyllids have been captured in our Magic Valley sites. Though we have found scarcely any psyllids in the Upper Snake sites, we did capture 4 psyllids in that region this week.
